To all wlw/n, it '11m/'1] concer/t.- rack-bar C has a rack F, which engages a Be it known that I, MELUN NLOVELL, a pinion g on the shaft ot an indicator-wheel citizen of the United States, residing at Erie, G, on the face ol' which are the ordinals, so in the county of Erie and State of Iennsylspaced that 'for each degree oll upward movevania, have invented certain new and useful ment given to the rack-bara different ordinal 55 Improvements in Cash Registering and Indiis displayed. catingMachines; and I do hereby declare the The construction so tar described is not my following to be a full, clear, and exact deinvention and will not be claimed as such. scription of the invention, such as will ena- On each ot the rack-bars C I place an addiio ble others skilled in the art to which it aptional rack, marked, respectively, l, 2, 23, 6o

My device is illustrated in the accompany- These racks are also alternated in position, ing drawings as follows: Thus, as shown, the rack at the right of the Figure l shows the machinein vertical lonmachine l has its cog-teeth facing outwardly zo gitudinal section on theline tra' in Fig. 2,with from the rack-bar.

On each ol' these Fig. 4f is a vertical transverse section ot' the shafts is a pinion @,which engages theproper registering mechanism on the line in Fig. rack ll), de.

The first four ot the shafts l, &c., are

containing nine key-levers. These groups connected, respectively, with the four hori- 40 are marked 122B, .3, and 4Q". Each ot' these zontal shafts 1E, d'c., by a spring ratchet- 9o groups of key-levers act upon vertically-movclutch device c', E', and ll, whereby as any able blocks lf, 2", 3, and 4.", and each block one ot the horizontal shafts l, dto., is reis the toot of a rack-bar C. The action oi' volved by an upward movement of its coneach key-lever in each group will raise the necting rack-bar C the register-shaft 1H, dre., superimposed block a certain fixed distance, connecting therewith, will be revolved the andthese distances are varied in gradative same distance; but when thehorizontalshaft succession from rightto left, so that the right- 1E, itc., is revolved by the downward movehand key-lever ot' each group will lift the ment oi' its connecting rack-bar the registerblock the minimum distance and the leftshaft will not bemoved. Retardingor brake 5o hand key-lever the maximum distance. Each sprin 7L arcemploycd to prevent momentivc Ico action disturbing the operation of the regisistering device, and these springs also act as pawls to prevent back movement of the wheels on which they act. Each of the register-wheels has nine teeth, and on the side of each of said wheels, except the top one 6h, there is a carrying-pawl which engages the next adjacent wheel above it, so that whenever any one wheel (except 6") has been turned once around it will move the next higher wheel one tooth forward. Now let the first group of key-levers 1B represent units, the next tens, the next hundreds, and the last thousands; or where the machine is used as a cash-register the first group of keys lB will represent cents, the next dimes, the next dollars, and the last tens of dollars. Now if the first key-lever on the right of the first group 1B is depressed the first foot-block lC will be raised one degree of its total traverse, and that will carry up the first rack-bar C the salne distance,`and that will move the first indicator-wheel so as to display the figure Il, and the first horizontal shaft lE will be moved one degree, and that will display the gure i on the rst dial h3. If in place of the first key-lever being depressed it had been the fifth, the operation would have been the same, only the parts would have moved farther, and the figure 5 would be displayed on the indicator-wheel and the register-disk. Whichever key-leverof any group may be depressed the corresponding action will occur. As soon as-the parts are released after'any action (by a proper releasing mechanism not a part of the present invention and not necessary to describe) they will return to the normal condition, except the registering parts, which are not permitted to react, the spring ratchet-clutches E H allowing the shafts 1E, &c., to react Without reacting the shafts 1H, &c. Therefore it will be seen that if key l of the group lB be again depressed the indicatorwheel will again display the figure 1, but the registering-disk on the shaft 1H will display the figure 2. Each shaft of the register device is free to be turned independent of the others; but whenever it has been turned one complete revolution its carrying-pawl h2 will move the next higher shaft one degree. The result of this arrar gement is that as the keys of any group are operated the register-shaft 1H, dec., connected with that group is turned to the extent proper to register the sum of the amounts indicated, and as soon as the said shaft has been turned one complete revolution the'next higher shaft is moved one degree. So it is that while the action of the keys of each group is carried by its connecting-shaft 1E, dsc., into the register independently of the action of the keys of the other groups, the register will indicate the sum of the amounts represented by all of the keys as they may have been operated upon.
